If you are giving scholarships or subsidies to black teenagers so they can eventually get into a university, that’s also DEI, so better subsidise their families so they can get a better primary education and upbringing… but that’s also DEI.
So you keep going back and the “solution” is basically to do nothing and keep the status quo.
Looking at this in terms of race is misguided. Don't do anything for "black people," just help "poor people" get better educations by giving more money to poor schools. A lot of "poor" schools are actually black schools, but not all, so more than just black people will benefit; and not all black people are poor, so we won't waste resources on those who already have them.
Defining DEI as "doing anything about the problem" and then saying that DEI opponents therefore don't want to do anything about the problem is a lazy bait-and-switch that I wish we would all recognize and stop doing.
What is wrong with helping poor people get better primary education? What is wrong with making university cheaper and more accessible?
These types of things should help black people, as well as hispanic, asian, or white people that start with a disadvantage.
Also, society can tackle problems like the study time gap https://fburl.com/oa3uenrr
